FR3021275A1 - DEVICE FOR PROTECTING SEATS OF A MOTOR VEHICLE WITH A FENCED PROTECTION WALL - Google Patents

Abstract

A protection device (D) equips a motor vehicle (V) having a row of seats (S1-S2), and comprises a tube (TC) installed behind the seats (S1-S2) and having a closed position in which it houses integrally a protective partition (CP) in a folded position similar to that of a folded fan, and an open position in which it allows a deployment of the protective partition (CP) behind the seats (S1-S2) by a drive rotating about a longitudinal axis (AL), into an unfolded fan protection position.

Description

The invention relates to motor vehicles, possibly utilitarian, and more precisely to certain protection devices which are installed behind the seats of a row in order to protect them. against objects behind them and potentially dangerous for the passengers they welcome. Some vehicles (automobiles), generally utilitarian, include a passenger compartment defined in particular by a floor on which are installed seats (generally of rank one) which must be protected by a protection device (or "stop load") so that the objects temporarily installed behind them do not come to hit their rear face, which could damage them or even hurt the passengers they welcome. In commercial vehicles, the protection device comprises a protective partition which is generally in the form of a rigid and fixed plate, possibly coupled to a grid in an upper part. This protective partition is generally secured to the vehicle structure (and more precisely to the floor and roof (or roof) and / or the side walls), just behind the rear face of the front seats (or rank one), which prevents the longitudinal translation of the front seats backwards (and thus can prevent optimal positioning of the driver's seat) and prevents its withdrawal when its presence is not justified (which may limit the load space). It is certainly possible to secure the protective device to the seats, and more specifically to the rear face of their seat, and not to the vehicle structure. But this is not optimal in terms of protection because loaded objects can drive the upper part of the protective partition and possibly pass between the latter and the roof (or roof). It has also been proposed to add kinematics to certain protection devices. But the latter is generally complex to understand and / or use for the user, and / or requires removal (or retraction) of the passenger seat to allow a 90 ° rotation drive around a vertical axis, of the protective partition.

The invention is therefore particularly intended to improve the situation. It proposes for this purpose a protective device for equipping a motor vehicle comprising at least one row of seats. This device is characterized in that it comprises a clean tube to be installed behind the seats and having a closed position in which it fully houses a protective partition in a folded position similar to that of a folded fan, and a position open in which it allows deployment of the protective partition behind the seats by a rotational drive about a longitudinal axis, into a position of unfolded fan protection.

This provides a very simple protection device to deploy (fan) and does not interfere with any longitudinal translations of the seats when its protective wall is folded. The device according to the invention may comprise other features that can be taken separately or in combination, and in particular: in a first embodiment, its tube may comprise an end equipped with fastening means capable of being secured to a floor of the vehicle and adapted to allow its positioning in a rectified position, substantially perpendicular to the floor; - Its protective partition may be adapted to be rotated about the longitudinal axis about 360 °, so as to have a substantially circular shape in its protective position; - Its fixing means may be adapted to allow a rotational drive of the tube between a folded position, substantially parallel to the floor, and its upright position. Alternatively, its fixing means may be adapted to allow a constant positioning of the tube in its upright position; - In a second embodiment, its tube may be adapted to be secured to a floor of the vehicle in a transverse position. In this case, its protective partition is adapted to be rotated about the longitudinal axis about 180 °, so as to have a substantially semicircular shape in its protective position.

The invention also proposes a motor vehicle, possibly of utility type, and comprising a floor on which are secured seats in a row and a protective device of the type shown above. For example, the floor of this vehicle may comprise a transverse housing in which is housed the protective device at least temporarily. Other features and advantages of the invention will appear on examining the following detailed description, and the accompanying drawings, in which: FIG. 1 schematically illustrates, in a sectional view in a transverse plane YZ, a vehicle Utility vehicle equipped with a first embodiment of a protection device according to the invention in a stowed position, Figure 2 schematically illustrates, in a sectional view in the transverse plane YZ, the utility vehicle of Figure 1 with its protection device in an extended position, FIG. 3 schematically illustrates, in a sectional view in a transverse plane YZ, a utility vehicle equipped with a second embodiment of a protection device according to the invention with its protective wall in a folded position, and Figure 4 schematically illustrates, in a sectional view in the transverse plane YZ, the vehicle automobi the utility of Figure 3 with the protective wall in an extended position. The invention aims in particular to provide a protection device (or "load stop") D for equipping a motor vehicle V comprising at least one row of seats. FIGS. 1 to 4 show diagrammatically a part of a motor vehicle V equipped with a first or second embodiment of a protection device (or "load stop") D according to the invention, placed behind a row of seats Sj (j = 1 or 2) secured to the floor PL (possibly via slides).

In the figures, the direction X is the longitudinal direction of the vehicle, which is substantially parallel to the lateral sides which comprise the side doors (or doors), the direction Y is the transverse direction of the vehicle, which is perpendicular to the longitudinal direction X, and the Z direction is the vertical direction of the vehicle, which is perpendicular to the longitudinal direction X X and transverse Y. It is considered in the following, by way of non-limiting example, that the motor vehicle is of the utility type. This is for example a van, possibly type said K1 or K2. But the invention is not limited to this type of motor vehicle. It concerns any type of motor vehicle having at least one row of seats to be protected by a protective device D. Therefore, the invention also relates to certain motor vehicles whose rear and / or intermediate seats can be retracted ( possibly in the floor) to allow the definition of a temporary loading floor. 20 The vehicle (automobile) V being a van here, it understands in its cockpit only a single row of seats. But it could have at least two rows of seats (including one front). Moreover, in the nonlimiting example illustrated in FIG. 1, the single row (a) comprises only one single-seater driver's seat (here placed on the left-hand side) and a single-seater passenger seat (possibly retractable and here located from right side). It should be noted that the rank one could comprise two single-seater passenger seats or a two-seater passenger seat (or bench seat). As illustrated in FIGS. 1 to 4, a protection device (or "load arrestor") D, according to the invention, comprises at least one CP protective partition and a TC tube intended to be installed behind the seats. Sj. The tube TC has a closed position illustrated in FIGS. 1 and 3 and in which it fully houses the protective partition CP in a folded position which is similar to that of a folded fan, and an open position in FIGS. 2 and 4. and in which it allows a deployment of the CP protective partition behind the seats Sj by a rotational drive about a longitudinal axis AL, to a position of unfolded fan protection. The longitudinal axis AL is here substantially parallel to the longitudinal direction X. In order to allow folding and deployment of the CP protective partition similar to the folding and unfolding of a fan, this CP protection partition must be made in a flexible material. In addition, this material must be resistant to withstand the pressures exerted by objects behind it and moving towards the front of the vehicle V. Therefore, the material may, for example, be plastic or composite. It will be noted, as illustrated in non-limiting manner in FIGS. 2 and 4, that it is preferable for the CP protective partition to comprise radial reinforcement rods TR from the longitudinal axis AL, so as to reinforce its structure and its ability to withstand the pressures. It will also be noted, although it does not appear in FIGS. 2 and 4, that the protective partition CP may comprise on its periphery at least one first fixing means intended to cooperate with at least one second fastening means secured to the vehicle V (for example on the roof or an upright or a side wall), to allow its temporary anchoring in at least one predetermined location of the vehicle V. At least two embodiments of the protective device D can be envisaged. In a first embodiment illustrated in non-limiting manner in FIGS. 1 and 2, the tube TC comprises an end which is equipped with fastening means MF adapted to be secured to the vehicle's V floor and capable of enabling its positioning in a vehicle. rectified position, substantially perpendicular to the PV floor (see Figure 2). It will be noted that in the example illustrated nonlimitingly in FIGS. 1 and 2, the fixing means MF are very advantageously adapted to allow a rotational drive of the tube TC between a folded position, substantially parallel to the floor PV and illustrated in FIG. 1, and the rectified position illustrated in Figure 2. To do this, the MF attachment means may, for example, be in the form of a hinge secured to one end of the TC tube and the floor PL, for example by screwing or welding. This makes it possible to fold down the tube TC with the CP protective partition folded, when one does not need the latter (CP). So that the TC tube is not prominent on the PV floor when it has been folded down, the latter (PV) may, as shown without limitation in FIGS. 1 and 2, comprise a transverse housing LT intended to house the protection device D temporarily, and preferably integrally. The term "transverse housing" here means a housing which is substantially parallel to the transverse direction Y. But in an embodiment variant not illustrated, the fixing means MF could be arranged to allow a constant positioning of the tube TC in its position. rectified. It will be understood that in this case the TC tube remains permanently in the vehicle V in a rectified position perpendicular to its PV floor (but of course with its protective partition CP is folded or deployed, as needed). In this first embodiment, and as shown in non-limiting manner in FIG. 2, the protective partition CP is preferably arranged to be rotated about the longitudinal axis AL by about 360 °. In this case, once it has been fully deployed and thus in its protective position, the protective partition CP has a substantially circular shape. In a second embodiment shown in non-limiting manner in FIGS. 3 and 4, the tube TC is able to be secured to the floor PV of the vehicle V in a transverse position. The term "transverse position" is understood here to mean a position which is aligned substantially parallel to the transverse direction Y. The protective partition CP is then arranged to be rotated about the longitudinal axis AL by about 180 °. In this case, once it has been fully deployed and is in its protective position, the protective partition CP has a substantially semicircular shape. The tube TC is here secured transversely to the floor PV via fixing means MF ', for example by screwing or welding. Moreover, and as in the case of the first embodiment, so that the TC tube is not prominent on the PV floor, the latter (PV) may, as shown in non-limiting manner in FIGS. 3 and 4, comprise a transverse housing. LT intended to house the tube TC permanently, and preferably integrally. It will also be noted, although it does not appear in the figures, that the tube TC preferably comprises a first part on which is rotatably mounted a second part, so as to allow access to the CP protective partition when the we want to deploy it. It will be understood that in order to open the tube TC it is necessary to unlock its second part of its first part (for example by actuating a hook), then it is necessary to rotate its second part with respect to its first part. Then, the deployment of the CP protective partition is rotated relative to the longitudinal axis AL.

Thanks to the invention, a protective partition can be very easily deployed and folded (and stored) behind a row of seats. In addition, when the tube can be folded or is lying on the floor permanently, it occupies on the floor a reduced space or even zero (in case of integration in a transverse housing), which does not penalize the space loading. In addition, the fan-shaped appearance is very attractive inside a vehicle.
